well, first of all remove from vehicle. most iac have 2 torx screws to remove it. use an old toothbrush or similar to clean it. do not put body of iac in any liquid or it will ruin it. just clean valve on end of iac. also do not push on iac valve, because it will mess up idle of vehicle. just clean the valve on end to remove carbon build up and dirt. you can use brake cleaner or throttle body cleaner for this. it is also a good idea to clean around throttle plate to remove carbon on throttle body itself. but do iac first and put back on throttle body. have a good day!

fast idle is many times caused by a engine intake vacuum leak, use a can of carb spray and spray the top of the engine for leaks, if u hit one u will hear the eng change idle speed, also look for split or leaking vacuum hoses.

before you drop tank again, check fuses & relay.then disconnect fuel line @ filter turn key to on position should hear fuel pump run and get gas stream out of line. if no flow from line new pump faulty be sure & remove negative battery cable first good luck.

If it's not idling and has problems starting, it's probably the IAC motor. It's located on the throttle body. Follow the airfilter box all the way to the engine, where the rubber flex hose attaches. The throttle body should be the first aluminum part you come to. Attached to the side you'll find small little aluminum part with a small wire harness attached. Unplug it, take the IAC motor off and clean inside with carb cleaner. This should fix the problem with the idle.

SOURCE: 02 mitsubishi eclipse p507 code.
P0507 - Idle Air Control (IAC) System RPM Higher Than Expected
This P0507 code is one that's sometimes triggered on vehicles that have electronic throttle control. That is, they don't have a regular throttle cable from the accelerator pedal to the engine. They rely on sensors and electronics to control the throttle. In this case, the P0507 DTC (diagnostic trouble code) is triggered when the PCM (powertrain control module) detects an engine idle speed that is greater than the desired (pre-programmed) RPM. In the case of GM vehicles (and possibly others) if the idle speed is over 200 rpm higher than expected, this code will be set.
Potential Symptoms: Most likely you'll notice the idle speed is higher than normal. There are potentially other symptoms as well. Of course, when trouble codes are set, the MIL (malfunction indicator lamp, a.k.a. the check engine light) illuminates.
Causes: A P0507 DTC trouble code may be caused by one or more of the following:
* A vacuum leak
* Leaking air intake after the throttle body
* EGR valve leaking vacuum
* A faulty positive crankcase ventilation (PCV) valve
* Damaged/failed/dirty throttle body
* Failed EVAP system
* Failed IAC (idle air controller) or faulty IAC circuit
Possible Solutions: This DTC is more of an informational code, so if there are any other codes set, diagnose them first. If there are no other codes, inspect the intake air system for air or vacuum leaks and damage. If there are no symptoms other than the DTC itself, just clear the code and see whether it returns.
If you have an advanced scan tool that can interact with the car, command the idle higher and lower to see if the engine responds appropriately. Also check the PCV valve to see if it's blocked and needs to be replaced. Check the IAC (idle air controller) if equipped, verify it's operation. If available, try swapping in a new throttle body to see if that fixes the problem. On Nissan Altimas and possibly other vehicles the problem may be fixed by having the dealer perform an idle air relearn procedure, or other relearn procedures.
